WAVE-MOTOR.

Specification of Letters Patent.

Patented Oct. 13, 1908.

Application filed December 28, 1906. Serial No. 349,768.

To all whom it may concern: c it known that I, JonN A. l\-fcl\lANUs, States, residing at Philadelphia, county of Philadelphia, and

State of Pennsylvania, have invented a certain new and scful Improvement in Wave- Motors, of Whidh the following is a specification.

My invention relates to a new and useful improvement in wave motors, and has for its object to provide an exceedingly simple and effective arrangement by which water or other fluid may be constantly pumped by the action of the waves and then forced through a turbine or other suitable motor, to which is coupled an electric generator whereby a constant electric current may be produced and conveyed to any suitable point.

W th these ends in view, this invention consists in the details of constru *tion and combination of clemcn ts hereinafter set forth .and then specifically designated by the claims.

In order thatthose skilled in the'art to which, this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawingforming a part of this specification, in which- Figure 1 is a plan view of my improved wave motor showing the operating mechai'iism thereon. Fig. 2, an elevation, the end of the central float being sectioned away at the line 9c.1: of Fig.1 to show that the interior of said float is hollow. Fig. 3, 2. diagrammatical view illustrating the use of a considerable number of secondary floats in connection with the main or central float.

In carrying out my invention as here embodied, I provide a central float A, to which 'are hinged the secondary floats B, in such manner that the movement of the waves will cause the secondar floats to swing upon their hinges, and n1 on the mam or central float I locate a number of pump cylinders C,

which are preferably pivoted so as to have a rocking movement thereon, the piston. rod D of said cylinders being pivoted to the blocks E, securedupon the secondary floats. By this arrangement any movement of the secondary floats relative to the central float will actuate the pumps C to pump water to the main pipe F, to which is attached the air dome G, and which also leads to the turbine or other motor H.

As the water from the various cylinders is pumpedinto the main pipe an even pressure will be maintained thereon through the medium of the air dome G, and this water passing through the turbine II will cause it to re volvc and impart motion to the armature of the generator I, and from said generator suitable conductors may be led to the shore or other suitable point for-supplymg electricity for working purposes.

As there are a number of pumps located upon the central float and some or all of them will at all times be in operation, it follows that a constant stream of water will be forced through the motor, the flow of which may be re ulated by suitable governors and relief VttIVOS," so that the minimum power will be utilized for generating the current while any surplus power will be thrown away, and as there is no ,cost of operation of such apparatus, this apparent waste of power is not objectionable.

One of the advantages of my present invention is that the floats will operate in comparat-ively shallow Water While generating power on a large commercial scale, and Where it is intended to operate a large plant from the current generated by this method, a number of such floats may be'anchored at a suitable distance from the shore, and the combined current from all of these floats transmitted to a central station and either be used directly upon the line wire of a trolley or other system or stored in secondary batteries from which it may. be drawn, asirequired.

' Having thus fully described my invention, What I claim as new and useful, is

1. In a wave motor of the character dcscribed, a central float, a series of secondary floatshinged thereto, pumps located upon the central-float, the piston rods of which are connected with the secondary floats, a water motor also located upon the-central float,

pipes for leading water from the pump cylinders to the motor and an electric generator adapted to be operated by the water motor,

as and for the purpose set forth.

2. In a water motor of the character described, a central float, a series of secondar floats hinged thereto, a series of pivoted cy inders located upon the central float, a series of. blocks located upon the secondary floats to which the piston rods of the cylinders are attached, a main pipe connected with all of the cylinders to recelve Water pumped therefrom, an air dome connected with said pipe for equalizing pressure upon the water, a turbine also connected with said pipe by which it is supplied with water and an electric generetor coupled to the turbine for converting the Water power into electrical power, as specified.

' In testimony whereof, I have hereunto ailixed my signature in the presenceol' two subscribing witnesses.
